This collection contains global in-situ sea surface underway measurements from the NOAA NCEI Surface Underway Marine Database (NCEI-SUMD, formerly the NCEI Thermosalinograph Database). The database was originally developed to facilitate understanding and access to a set of quality controlled in-situ sea surface temperature (SST) and salinity (SSS) measurements collected by thermosalinographs (TSG). The database was later expanded to include surface underway non-TSG data, such as meteorological data from the vessel-mounted meteorological packages, microplastics data and data from Unmanned Surface vehicles, such as Saildrones and Wave Gliders. Data were in situ underway data collected by thermosalinographs (TSG), meteorological packages and other sensors from 1989 to the present from more than 450 platforms. These data are from multiple data assembly centers, including the Center for Ocean-Atmospheric Prediction Studies (COAPS; TSG data from the Shipboard Automated Meteorological and Oceanographic System (SAMOS)), Institut français de recherche pour l'exploitation de la mer (IFREMER; English: French Research Institute for Exploitation of the Sea; TSG data from The Global Ocean Surface Underway Data (GOSUD)), Atlantic Oceanographic & Meteorological Laboratory (AOML-TSG data) and NOAA National Centers for Environmental Information (NCEI). When duplicate data were found with different resolution, the data with the highest sampling resolution were selected. All data were converted to common netCDF format, following the Climate and Forecast (CF) and Attribute Convention for Data Discovery (ACDD) conventions and following the NCEI netCDF 2.0 trajectory feature type. All data were processed using the same 11-step quality control procedures and criteria and flagged using a two-level flag system to provide a well-organized, uniformly quality-controlled TSG dataset for the user community.},
